@karel: If you want me to take your repeated close votes like this one serious, I expect you to take my repeated and well grounded criticism equally serious. Your "three strikes" come-back is, quite frankly, childish.

Just because a question contains certain key words among others, doesn't mean it's a duplicate of a question that is only about those key words.

That being said, I'm grateful for your bounty on my Skype answer, although more as a means to highlight its current relevance than out of a sense of personal pride.

(In fact I'm much prouder at some of my answers with 5–10 up-votes than the Skype answer that I mostly copied and sourced from Gunnar.)

I don't like being nagged. I find it disagreeable. I not so dumb that I don't know exactly what would happen just because I told someone who was being a nuisance to shut up. Also he doesn't even take the time to read the both the question and the accepted answer before he reacts.

This is the behavior that Foerster thinks he's more mature than. If you want to be wrong, be wrong and I'll put up with it. I don't care. Just don't start nagging me and make a nuisance of yourself.

@karel Did you take the time to read the question and the accepted answer? Because your close vote makes me believe the opposite.

The answer starts out with a recommendation to clean up duplicate repository definitions. Then, for the actual solution it goes on to recommend the complete removal of all instances of a specific repository and all its packages.

That's quite different from the question that you linked.

And I don't think I need to re-read the linked question and its answers since I spent quite some time on it in the past.

If you disagree that the last half of the accepted answer was crucial in the solution of the issue presented in the question, so be it, but I find that less plausible with the evidence at hand.

Do you have any idea how many How can I fix apt error "W: Target Packages ... is configured multiple times" have been accessed on this site including the deleted ones? Is it hundreds, is it thousands already? Why do need a database that is made of thousands of duplicates of each canonical error message? As you noted a few comments back the bad answers sometimes get many more votes than the good answers. Except for canonical questions (hopefully).

@karel I'm not sure what argument you're trying to make there. Everything I can think of is unrelated to whether this question in particular should be closed as a duplicate of "W: Target Packages ... is configured multiple times".

This is why I let him get away with it twice. Because he thinks he's right and he's entitled to his opinion. The third time is too much. I obviously read the other two comments and silently disagreed with them, so now he's persecuting me to stop reviewing "W: Target Packages ... is configured multiple times" by nagging me every time I review one. When I see a question that is duped with 4 close votes to the wrong target I don't nag and pick a fight, I cast the 5th close vote correctly.

@karel Each instance was a separate instance of an imho unrelated dupe vote and my argument was each time based on the specific combination of questions and answers. That all of the dupe votes stemmed from you and pointed to the same question was entirely unimportant to me. I'm arguing for or against causes and not people and I try to take the specific circumstances of each event into account.

The world according to you is that if the question is a legitimate duplicated you can't accept it unless I pin it with every other duplicate and don't ask any other reviewer for help because it won't be forthcoming. The correct thing for you to have done if it's a multiple duplicate question is to not throw the bogus ancillary comment and dupe it yourself to one of the other legit duplicate targets. I don't care if you won't help, just don't nag or else pitch in and pin another duplicate target.

I'm really tired of people throwing close votes around to "solve" questions. Close votes are only for question we have already solved or cannot reasonably solve in scope. If a duplicate doesn't solve the OP's entire problem, then it's not a duplicate.

@karel Although I'm not a big fan of close votes for dupe reasons, I have to admit that you are right with one point : we have a whole lot of topics which have already been answered before ... or better : there is nearly nothing new being asked these days which hasn't already been answered ... and that leads to one general point : what to do with Ask Ubuntu in the future ? Mostly new users come here to get a current problem solved and hence ask their question ... @Seth

@Seth I mean, why not letting new users ask their questions and getting answers ... or, the other way around, close nearly all new questions at once, because they (in nearly all cases) have already been answered before ?

@cl-netbox While that is true for a good chunk of incoming questions, you're missing one important point: the relatively rapid change of technology and software features alone will always result in truly new and original questions.

If anyone in chat is using Totem on 16.04, can you please post the output of apt list --installed | grep -e gstreamer -e totem so I can compare installed plugins? I'm trying to figure out why I can no longer play MP4 videos.

My troubleshooting so far is here: askubuntu.com/questions/1008762/… Totem used to play them, and the necessary plugins are installed, but I've clearly broken something and cannot get things to work again.

@DavidFoerster I'm trying to compare my installed plugins with someone else's (which does play MP4s). Is that something I can look up on the packages list by myself? It appears to be a complete list of all possible packages, which does not help me.

@JavaFan This is usually something you enable in your computer's BIOS/UEFI. Look for it just as you are booting up, it's usually accessed during the first few seconds after you switch the computer on. You have to press a certain key (usually F8 or DEL, something like that). Hope that helps.

@AndyK Maybe try a bash alias? echo "alias python3='$PWD/python3'" >> ~/.bash_aliases && source ~/.bash_aliases (but test it to confirm it does not interfere with other commands, such as when the path is unnecessary).

I switched to Russian keyboard via loadkeys ru command and now cannot switch back.

So far I've been stuck on Cyrillic... Doe...

@dessert and others... this one looks like a dupe. I posted the target in the comments below the question and OP abides, but wasted my close-vote :( https://askubuntu.com/questions/1009050/ubuntu-17-10-lid-close-different-behaviros-on-ac-or-battery
